Re: [PATCH i386 3/8] [AVX512] [2/n] Add AVX-512 patterns: Fix missing `v' constraint.

Here's 2nd subpatch. It fixes missing `v' constraints.

Is it Ok?

Testing:
  1. Bootstrap pass.
  2. make check shows no regressions.
  3. Spec 2000 & 2006 build show no regressions both with and without -mavx512f option.
  4. Spec 2000 & 2006 run shows no stability regressions without -mavx512f option.

Thanks, K

PS. If it is ok - I am going to strip out ChangeLog lines from big patch
